well your first thing is determining if you want a laptop or a desktop. Desktops offer MUCH more bang for the buck. a laptop with similar specs to a desktop will cost twice as much.
Do you have a budget? a laptop with those specs will probably cost over a thousand dollars, while you could get a desktop with those specs (depending on graphics card) for about 600. (700 with cheap peripherals like monitor, keyboard, and mouse)
If you are set on a laptop, i would look at asus stuff. They make their own chipsets and usually sell durable and reliable products. Companies such as Acer are cheaper with similar specs, but they have arguable build quaility/reliability.
The best way to get a good deal on a desktop is to build your own. It honestly is not that hard and if you just go in step by step you should have no problem if you decide to do so.
The best bang for buck processor is the i5-2500k, which costs at most online retailers from $200 to $220. 8GB of desktop ram costs about $40. I can make more recommandations if you want to take this route, but you should tell us really what you want more first.
